Embodiment 1
[0041] see Figure 1 to Figure 4 As shown, Embodiment 1 of the present invention provides a performance test device for a magneto-rheological shock absorber, which is used for the performance test of a magneto-rheological shock absorber for automobiles, including a power unit, a guide mechanism, a force sensor 100 and a displacement sensor 102 The power unit is used to make the magnetorheological shock absorber 126 to be tested reciprocate along the guiding direction of the guide mechanism; the force sensor 100 is used to detect the magnetorheological shock absorber to be tested when the The generated damping force information, that is, the information of the magnitude of the damping force produced by the magneto-rheological shock absorber to be tested; the displacement sensor 102 is used to detect the reciprocating motion of the magnetorheological shock absorber to be tested, The displacement information of the shock absorber, that is, the information of the displacement chan...
Embodiment 2
[0060] The magnetorheological shock absorber performance testing device in this embodiment is an improvement on the basis of Embodiment 1. The technical content disclosed in Embodiment 1 will not be described repeatedly, and the content disclosed in Embodiment 1 also belongs to the content disclosed in this embodiment. .
[0061]In this embodiment, the MRA performance testing device also includes an acceleration sensor, which is used to detect the acceleration information of the MRA to be tested when the MRA reciprocates, that is to say, The acceleration of the magneto-rheological shock absorber to be tested is measured in real time. Specifically, the acceleration sensor is electrically connected to the computer, and the computing mechanism is also used to receive the acceleration information of the magnetorheological shock absorber to be tested sent by the acceleration sensor in real time. The acceleration sensor is installed on the reciprocating guide plate 103 to detect th...
